Procedure

To a solution of the above 2-benzyloxycarbonylamino-5-(1-oxo-1,3-dihydro-isoindol-2-ylmethyl)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3,6-dicarboxylic acid di-tert-butyl ester (9 mg, 0.014 mmol) in methanol (2 ml) was added 10% Pd/C (4 mg). The mixture was stirred under hydrogen (1 atm.) for 3 hours and then filtered. The filtrate was evaporated in vacuo affording 6 mg (93%) of 2-amino-5-(1-oxo-1,3-dihydro-isoindol-2-ylmethyl)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3,6-dicarboxylic acid di-tert-butyl ester as a solid.
